Robert Hartmann describes himself professionally as an architectural designer. Based in Racine, Wisconsin, he has designed many of the city’s downtown storefronts. More important for me, has been as an architectural archaeologist as I work on my Frank Lloyd Wright books. This summer Hartmann — an avid baseball fan — hit one home run after another after I sent him high resolution copies of Wright’s drawings related to Penwern, the Fred B. Jones estate on Delavan Lake, Wisconsin (1900 – 1903) and we visited the estate twice.

A week ago he hit a veritable grand slam home run in a late night email. He had greatly enlarged one of Wright’s drawings for the unrealized “scheme 1” cottage for Henry H. Wallis, designed in September, 1900, the month before Penwern would be designed for a nearby lot. Wallis, the premier land salesman on the south shore of Delavan Lake was an early client and patron of Wright. Wright proposed an arched porte-cochère for Wallis (drawing above). The house, as built, (below) differs in several details including the lack of the porte-cochère as well as the lack of stone piers at the corners of the house. Wallis sold the house at completion to the GoodSmith brothers and it is now known as the Wallis – GoodSmith House (the open porch facing the lake is a modern addition):

Wallis-Goodsmith House

Hartmann was intrigued by faint pencil marks by Wright above and to the left of the proposed porte-cochère and brought them to a finished state. He discovered that Wright had drawn both a covered walkway above it and a tower to the left of it:

All three of these unrealized details — the arched porte-cochère, the covered walkway above it, and the tower are prominent details at Penwern:

There are two possible explanations for the faint pencil sketches of the walkway and tower on Wallis scheme 1. Did Wright propose these features for Wallis before building them for Jones as Hartmann wonders? Or did he simply use a copy of the discarded Wallis plan on which to sketch ideas for the Jones house as Patrick Mahoney suggests, pointing out that Wright did just that using drawings for the Walter V. Davidson House in Buffalo (1908) when designing the Oscar M. Steffens House in Chicago a year later?

Hartmann made several other significant discoveries about Penwern this summer:

-Wright’s drawings for the gatehouse show a semi-circular wall east of the water tower. Today only half the wall stands. That discrepancy intrigued Hartmann enough to mention that to Sue and John Major, stewards of Penwern. They asked Bill Orkild, their contractor, to do some digging. He discovered the foundation of the missing portion of the wall as well as irrigation pipes from the 1903 greenhouse, which was torn down in the 1970s. There are now plans to make the wall whole again. The missing portion was apparently lost when strips of the east and west sides of the estate were sold in 1989 by a previous owner.

-Wright’s plan of the first floor of the main house shows curved walls for the large front porch (facing the lake) of the main house and the two side porches. Yet they were built straight. The Majors and John O’Shea, who was steward of Penwern from 1989 – 1994 had the porches rebuilt as shown on the drawings but the question remained why there was a discrepancy between the drawing and the walls as realized. Hartmann, again greatly enlarging the Wright drawings, found faint pencil lines bisecting the curved walls, with right angles connecting them to the porches. He surmises that Wright realized, or was convinced by his draftsmen or the contractor, that the curved walls would be difficult to build so he changed the final design to straight walls with the pencil marks, rather than make an entirely new drawing.

-Hartmann pointed out that there are fewer rows of boards and battens on the front of the stable than indicated on drawings of the structure. And, the drawing does not seem to take into account the gentle slope of the land in front of the stable. Does this mean that Wright had not seen the land for himself or that he did not supervise construction of the building? Hartmann also pointed out that whereas early photos of the front of the stable and the drawing show only two windows at each end, at some point it was determined that it was too dark inside the stable, and a second pair of windows was added just below.

Copies of Wright’s 17 surviving drawings for Penwern can be viewed at: www.penwern.com My book about Penwern will be published by the Wisconsin Historical Society Press in the spring of 2019. The book could not be possible without the help of countless people including Hartmann, Mahoney, and Orkild. For that reason the Acknowledgments are one of the most important parts of the book for me to accurately write.

I shot this panoramic photo of the view in three directions from a guest bedroom at Frank Lloyd Wright’s Fred B. Jones house (“Penwern”) on Delavan Lake, Wisconsin this morning. It was perhaps my last research trip to Penwern before the January 15 deadline for the manuscript for my book about Penwern which will be published by the Wisconsin Historical Society Press in spring 2019.

I am currently reviewing voluminous notes about Penwern that I have accumulated since starting the project in 2013 and rediscovering important points. Newspaper microfilm gives us the only definitive documentation of a visit by Wright to the lake…in 1905 while preparing to design a home for A.P. Johnson of Chicago. The A.P. Johnson House was the last of the five Wright homes on the lake.

The microfilm also clarifies the timeline for the four Wright buildings at Penwern. There are 17 surviving drawings. The drawings for the boathouse and the first floor plan for the house are dated October, 1900. One stable drawing is dated March 24, 1903. The microfilm dates completion of the house by the end of June, 1901 and the boathouse in spring, 1902. The gate lodge was constructed in 1903, the stable the next year.

The drawings are construction drawings, not presentation drawings. In his autobiography Wright mentions regret about the number of drawings he discarded. Mark Peisch theorizes that many drawings were lost or thrown out in the move from the Oak Park Studio to Taliesin, in his 1964 book “The Chicago School of Architecture.” I do not believe that drawings were lost to either fire at Taliesin: it is not likely that the Penwern drawings would have been kept in separate places and the surviving drawings show no sign of fire or water damage.

I saw something curious in the archive of Frank Lloyd Wright presentation and construction drawings at the Avery Architectural Fine Arts Library at Columbia University while doing research there early this week. I had never run across a cost estimate on one of Wright’s presentation drawings before. The estimate is smack in the middle of one of the drawings for the Stephen A. Foster Cottage and Barn (1900) on Chicago’s south side. The estimate for $3500 is equivalent to about $103,000 today. The website I use for cost comparisons is:

I was interested in looking at the Foster file because the house slightly predates the commission for Fred B. Jones (Penwern) on Delavan Lake, Wisconsin which I am writing about. The Foster “Cottage” and three of the four buildings Wright designed for Jones have flared or raised ridge rooflines, thought to be a Japanese design influence.

Perhaps it was not uncommon to have a cost estimate on a drawing, but this was the first time I had seen one. Incidentally, isn’t a fact that Wright never brought buildings in over his initial cost estimate, or am I mistaken?

The sixth iteration of SC Johnson’s annual The SC Johnson Gallery: At Home with Frank Lloyd Wright exhibition opens today in Fortaleza Hall on the company’s campus in Racine, Wisconsin. The centerpiece of the exhibition, titled On the Wright Trail, is the display of 26 miniature scale models of Wright’s architecture by retired architectural draftsman Ron Olsen of Janesville, Wisconsin. One of the models is of the gate lodge at Penwern, Wright’s estate for Fred B. Jones on Delavan Lake, Wisconsin (1900-1903):

The exhibition coincides with both the summer-long observances of Wright’s 150th birthday (June 8) and the inauguration of the Frank Lloyd Wright Trail in Wisconsin. A ceremony marking the launch of the Trail was held May 10 in the Great Workroom of Wright’s landmark SC Johnson Administration Building (1936). Olsen and his wife, Judy, were photographed when they saw the exhibition for the first time after the Trail ceremony. The exhibition includes a video interview with Olsen:

“SC Johnson is proud of its Frank Lloyd Wright-inspired architecture,” said Kelly M. Semrau, Senior Vice President – Global Corporate Affairs, Communication and Sustainability, SC Johnson. “In celebration of Wright’s birth in Wisconsin 150 years ago, we are thrilled to offer visitors of On the Wright Trail a unique opportunity to study the architect’s design practice across different areas, media and time.”

Frank Lloyd Wright designed semi-circular outer porch walls for Penwern, the Fred B. Jones House on Delavan Lake, Wisconsin (1900-1903), but the walls were either built straight or modified from his plans early in the life of the house. Jones is shown near the straight east porch wall in an undated photograph. The house was completed in 1901; he died in 1933.

The east and west (side) porches now have semi-circular outer walls, as indicated on Wright’s drawings for the house. (The drawings can be viewed on Penwern’s magnificent website, www.penwern.com ) Sue and John Major, stewards of Penwern since 1994, commissioned master builder Bill Orkild to rebuild the side porches to Wright’s plan this spring. The work was completed just a week ago. The outer wall of the front porch, facing the lake, was changed from straight to semi-circular by John O’Shea, the fourth owner of the house, between 1989 and 1994. The front porch is on the right side of the first photo below:

The semi-circular design brings a unified design element back to the house because it echoes the dramatic arch over the front porch and the arched porte-cochere.

Orkild photographed the east porch during reconstruction:

He also fashioned the diamond-shape accents shown on Wright’s drawings.

The next question for the Majors to ponder with Orkild is whether the walls on the insides of the porch are load-bearing. The walls are not shown on Wright’s plans. Removing them would allow for more dramatic vistas to the east and west from the front porch. It is possible that the porches were screened in with these walls after Jones lived in the house to shelter himself and his visitors from mosquitoes.
